Nader Circuit Breaker

When designing and selecting low-voltage circuit breakers, the general principles that need to be considered are: Determine the type of circuit breaker selected according to the load nature, fault category and line protection requirements of the low-voltage power distribution system, and comply with ...

Many netizens proposed that after the L line is introduced from the N line of the circuit breaker, the current of the series circuit is equal everywhere, so the protection of the circuit breaker will not be affected. For this reason, I specifically add this part to illustrate. Lets look at the pictur...

If there is no leakage and the line is tightened, the neutral line burns badly, then the neutral line return current is too large! For example, on the same working circuit, when installing wires, several live wires will be pulled to various devices, while the neutral wire only shares one. In the work...

The contact is not in good contact. After the power failure, the incoming and outgoing wires must be tightened again. There may be a quality problem with the air switch itself. It is recommended that you replace it with a larger capacity air switch, and then be sure to plug in the grounding plug inst...

Vacuum circuit breakers are mostly used in high-voltage switchgear, which refers to a circuit breaker that uses vacuum as an arc extinguishing and insulating medium to open and close current in a vacuum vessel. Since the advent of vacuum circuit breakers in the early 1960s, with the improvement of va...
